FIELD: energy.
SUBSTANCE: invention relates to power engineering. Device to actuate load, containing multispool gas turbine, containing high-pressure compressor and high-pressure turbine, connected to each other by first shaft, low pressure compressor and working turbine, connected with provision of driving force transmission to each other by second shaft, passing coaxially to first shaft. At that, device additionally contains load coupling, connecting working turbine with load with provision of driving force transmission, and comprising two-speed rotary reduction gear, made with possibility to interact with said load to provide driving force transmission and exit from said interaction for slow rotating of load or to rotate low pressure compressor with provision of driving force transmission during washing in decommissioning mode. Invention also discloses method of washing in multi-spool gas turbine decommissioning mode, as well as method of multi-spool gas turbine and load connected therewith slow rotating.
EFFECT: invention increases gas turbine washing efficiency.
